This Solid Unshielded CL3P Fire Alarm Cable is a premium low-voltage wire designed for critical fire alarm, security, and communication systems, including burglar alarms, public address systems, intercoms, telephone stations, access control, instrumentation, nurse call, and other power-limited low-voltage circuits. Built with 100% solid pure copper conductors, it ensures maximum conductivity and reliable signal transmission for uninterrupted system performance. Rated Class-3 (CL3), this cable is ideal for demanding fire alarm and security applications. Its CMP/CL3P/FPLP Plenum-rated flame-retardant jacket provides superior fire protection and minimal smoke/toxic emissions in air-handling spaces such as ceilings and HVAC ducts. The UV- and moisture-resistant jacket allows safe indoor and outdoor use, though the cable is not suitable for direct burial or long-term immersion. Designed for ease of installation, the round, smooth jacket with rip cord allows effortless pulling through corners and conduit. Fully UL/ETL certified and RoHS-compliant, this solid unshielded CL3P cable combines optimal copper performance with rigorous safety standards for commercial and residential low-voltage circuits.
